The plants depicted in the images below are rather
arbitrarily included here. Gayophytum diffusum is so broadly
defined (note the key in Jepson Manual).that it can accommodate plants
exhibiting some of the features of a number of other species in the genus.
Gayophytum populations from Steens seem particularly difficult to assign
to species. For example, the images below represent plants that show
tendencies toward either G. decipiens or G. racemosum (leaves
longer than internodes, leaves and fruits erect to ascending, flowers small,
fruits sessile or with a stout narrowed sterile portion, fruit compressed [but
not as flat as G. humile]).
